Chrysanthemum plant named ‘Gedi One Ylsap’

ABSTRACT

A new and distinct Chrysanthemum plant variety characterized by a decorative type inflorescence, consistent flowering response to short days, blooming consistently after 49 days of short day length, free branching habit, yellow ray florets which resist fading with age, and a very uniform round growth habit.

LATIN NAME

Dendranthema morifolium

VARIETY

‘GEDI ONE YLSAP’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, herein after referred to by the cultivar name ‘GEDI ONE YLSAP.’

This new cultivar was discovered in the inventor's field in Belgium in October 1997. The new cultivar was discovered as a naturally occurring mutation on a single branch of the parent variety, ‘Sapiro’, which is unpatented in the United States.

Asexual reproduction of the new cultivar by apical tip cutting and meristem tissue culture was performed in Oxnard, Calif. and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘GEDI ONE YLSAP’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observe and are determined to be the unique characteristics of ‘GEDI ONE YLSAP.’ These characteristics in combination distinguish ‘GEDI ONE YLSAP’ as a new and distinct Chrysanthemum:

1. Decorative type inflorescence;

2. Consistent flowering response to short days, blooming consistently after 49 days of short day length;

3. Free branching habit;

4. Yellow ray florets, resisting fading with age; and

5. Very uniform round growth habit.

Plants of the new cultivar are similar to plants of the parent cultivar, ‘Sapiro,’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Sapiro’ in the number of blooms and the color of the ray florets. The new cultivar has slightly less blooms, as well as different colored ray florets, compared to the parent variety.

The new cultivar can be compared to the Chrysanthemum cultivar ‘Dark Veria’ (disclosed in U.S. Plant Pat. No. 10,215). However plants of the new Chrysanthemum differed from the plants of the cultivar ‘Dark Veria’ in the following characteristics:

1. New cultivar naturally blooms approximately 1 week later than ‘Dark Veria;’

2. New cultivar is taller and wider than ‘Dark Veria;’

3. New cultivar has a more round plant shape and greater branching than ‘Dark Veria;’ and

4. New cultivar has more blooms per flowering branch ‘Dark Veria.’

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph shows a plant of ‘GEDI ONE YLSAP’ grown in a 2 gallon container. One cutting was used in the pot, planted mid May and grown under outdoor field conditions.

DETAILED BOTANICAL DESCRIPTION
